SDK Rollup not updating on open (+) after (-)

[klvnk]

I have a rollup with win32 List View in it which is not redraw if you close (-) and open (+). The weird thing is it also doesn't redraw other controls in the window either. Anyone else solved this problem or know how to intercept the rollout open close.

solved it, the window had Clip Children set to true 🙄

A Win32 Listview? C++? Which Max Version?

Did you set the WS_CLIPCHILDREN style yourself? Max SDK doesn't set this style by default. It sets WS_CLIPSIBLINGS, but if you remove this style it may cause some controls to flicker.

I do Rollout::UpdateLayout(TRUE) on rollup+ which also helps me control the "resizing" issue.

Found a hack, You can intercept the close/open from the dlg proc when it's rolling up or down it posts a

WM_SHOWWINDOW msg (wparam = 0 -> closed = 1 open) it also sends WM_WINDOWPOSCHANGED && WM_WINDOWPOSCHANGING messages

though I can't get the ui to draw with WS_CLIPCHILDREN set

no a big issue as there isn't any ficker with it, I didn't actually set it was copied over when I pasted in the resource 😎 honest indian!
